Hi All,
On a new installation of bacula, interfacing with three LTO2 drives
through an ADIC Scalar 100 autochanger, I've come across the problem
where multiple jobs are requesting the same volume on different drives.
This used to be a problem prior to 1.38.6-b1 but I'm running 1.38.9
here. I doubt this is a race condition, as this happens after the first
job is well underway.
Example error:
------------------------
05-Jun 08:50 sbgrid-sd: FS4_XRAY.2006-06-05_07.05.29 Warning: Volume
000014L2 is in use by device "LTO2A" (/dev/nst0)
05-Jun 08:50 sbgrid-sd: Please mount Volume "000014L2" on Storage Device
"LTO2B" (/dev/nst1) for Job FS4_XRAY.2006-06-05_07.05.29
